Description
Technical Field
The invention belongs to the technical field of fire extinguishment, and particularly relates to a chemical coolant and application thereof in aerosol extinguishment.
Background
As a new fire extinguishing agent, the hot aerosol fire extinguishing agent faces an important problem in application, namely secondary damage may occur in the fire extinguishing process. The hot aerosol fire extinguishing agent generates aerosol through combustion reaction, which is exothermic reaction, so that higher temperature is generated. If no cooling measures are taken, flames or sparks are sprayed back at the fire extinguishing device port, so that the temperature of the protected space is raised, and combustible materials can be ignited. The high-temperature aerosol can greatly hurt or damage people and objects in the protection space, and when the temperature is high, the spatial distribution of the aerosol is easy to be uneven, so that the fire extinguishing effect is influenced.
In order to eliminate the high-temperature flame generated by the combustion reaction, the most practical and effective method is to add a coolant substance with large heat absorption capacity on the path of the hot aerosol, so that the temperature of the aerosol is obviously reduced from 1000 ℃ to below 400 ℃. It does not change the reaction speed of the oxidation-reduction reaction of the fire extinguishing agent and does not influence the ignition performance and combustion performance of the agent. The added coolant substance can be decomposed by heat generated by the fire extinguishing reaction, and the coolant itself can be decomposed to generate new aerosol components such as phosphate and inert gas (N) 2 ，CO 2 ) The aerosol concentration is increased, which is helpful to improve the fire extinguishing efficiency, and simultaneously eliminates the flame and residues from being sprayed out of the product.
The inventor researches and discovers that the existing coolant is mainly an organic component, can not effectively reduce the outlet temperature of aerosol and improve the fire extinguishing capability, and can not meet the safe use requirements in various practical scenes, which puts higher requirements on the design of the coolant. The high temperatures of the aerosol outlets are not fully utilized to produce new aerosol materials with high fire suppression capabilities. And the existing coolant has unsatisfactory cooling effect and fire extinguishing capability, so that the outlet temperature of the aerosol fire extinguishing agent is high and the fire extinguishing capability is not fully exerted.
Disclosure of Invention

The invention also relates to a preparation method of the chemical coolant, which is characterized by comprising the following steps:
s1, crushing and sieving raw materials, drying, mixing according to a proportion, and adding methanol for uniform mixing;
s2, granulating the materials obtained in the step S1 through a screen, and drying to obtain coolant drug particles;
and S3, the coolant particles obtained in the step S2 are flaked by a tablet press to obtain columnar coolant particles.

The invention has the following beneficial effects:
the coolant provided by the invention takes the organic flame retardant as the main raw material, and is decomposed to generate CO 2 、N 2 、H 2 Inert gases such as O, which can participate in extinguishing fires and enhancing the dispersion of aerosols. The added phosphate can be subjected to endothermic decomposition at high temperature to generate a decomposition product with volatility, and the decomposition product and free radicals or active groups such as H, HO, O and the like generated in the combustion process have chemical inhibition and negative catalysis effects, so that the combustion chain reaction is interrupted to extinguish the fire; in addition, the phosphate powder falls on the surface of the combustible material, and is subjected to chemical reaction, and a glass-like coating layer is formed under the action of high temperature, so that oxygen is isolated, and further, the fire is choked and extinguished. The K-containing additive generates CO during the endothermic decomposition reaction 2 、H 2 The inert gases such as O and the like and the oxides of K have the functions of reducing the oxygen concentration and isolating the oxygen, the oxides of K have the functions of capturing free radicals such as H, HO, O and the like, the free radical in the flame is consumed more quickly than the production speed, the burning free radical is quickly consumed, and the chain reaction process is terminated. The decomposition products of the coolant increase the concentration of the aerosol, and act synergistically with the aerosol generated by the aerosol generator to extinguish a fire. The organic flame retardant, phosphate and K additive can absorb a large amount of heat while decomposing, so that the nozzle of the device can be effectively reducedTemperature.

The data in the table are the discharge amount, discharge temperature and fire extinguishing time of the coolant prepared in the examples and the comparative coolant. It can be seen that the combined phosphate and organic flame retardant gave a higher level of coolant spray than the non-phosphate spray, indicating an effective reduction of residue. It can also be seen by comparison that the device nozzle temperature for phosphate containing coolant is below 450 c, while the non-phosphate containing coolant and ceramic ball outlet temperature is above 500 c. The highest temperature of the ceramic balls used as the coolant is 643 ℃, and the fire extinguishing failure is mainly caused by the limited heat absorption capacity of the ceramic balls and the inability to increase the concentration of aerosol; the fire extinguishing time of the device containing the organic flame retardant and the phosphate coolant is within 20s, while the fire extinguishing time of the device without phosphate coolant is 25s, and the fire extinguishing device with ceramic balls fails. Comparative example 1 not only the nozzle temperature was high when the coolant was all inorganic flame retardant, but also the fire extinguishing failed; the fire extinguishing failure in comparative example 3, although the nozzle temperature was low; the nozzle temperature of comparative example 2 was higher and the fire extinguishing time was longer. The addition of phosphate not only effectively reduces the outlet temperature but also improves the fire extinguishing ability.

Within the technical scope of the present disclosure, the technical solution and the invention concept according to the present disclosure are equivalent to or improved from the above description, and all the equivalent changes or modifications are included in the scope of the present disclosure.
